PIPE THREAD CUTTING DIES
Dies is one tool used to create screw threads, which is called threading. Many are cutting tools; others are forming tools. A die is used to cut or form the male portion of the mating pair (e.g. a bolt). The process of cutting or forming threads using a die is called threading.
PRODUCT INTRODUCTION
Pipe thread cutting dies is one kind of dies. As everyone knows, pipe threading machine is one pipe tool which is widely used on pipe connection aspect, threading machines are very popular because they make it possible to get impeccable results in numerous procedures like welding, and cutting etc. At the same time, it is an ideal solution to use threading machine to get a guaranteed effect. Among all spare parts from pipe threading machine, dies are the most important part. As a vulnerable part, there are many classifications for dies. Based on different material, there are carbon dies, alloy dies and HSS (high-speed-steel) dies; for applicable objects, dies can be categorized into pipe dies and bolt dies; due to the different pitch of screw, there are BSPT dies, NPT dies, and METRIC dies; well for the specification, dies have different capacity for different pipe size. General speaking, they are 1/2″-3/4″ dies, 1″-2″ dies, 2 1/2″-3″ dies, 2 1/2″-4″ dies, 5″-6″ dies.
PRODUCT FEATURE
Dies manufactured by TUWEI are High-Speed-Steel dies, High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is often used in power-saw blades and drill bits. It is superior to the older high-carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness). This property allows HSS to cut faster than high carbon steel, hence the name high-speed steel. Based on the High-speed steel material, through a series of processes such as grinding machine milling machine heat treatment, Tuwei produced high quality dies with the hardness is 55~60HRC. In the prototype stage, we do fatigue testing in our laboratory, we tested short pipe with short threads, and long pipe with whole threads, the dies are still in good condition after making more than 5000pcs threads, when make 8019 pcs threads, the dies worn. We sent many samples to many customers and construction site in China and other countries, to search the feedback before mass production. Now we are sure that TUWEI dies have a good quality.
PRODUCT USE
1. Push open Lever and release to set initial position.
2. Clipping slide link and die head, slide the slide link until the open lever set in.
3. Install dies to mark on side of dies. Die numbers 1 through 4 on the dies must agree with those on die head. Adjust die head size bar until the index line on lock screw or link is aligned with proper size mark on size bar. Then tighten clamp lever
4. With die head in working position and Pipe Cutter and Reamer in upright position, switch the power ON.
5. Feed Carriage towards Front Chuck to bring die head against end of pipe. Continue to apply pressure to hand
wheel to start threading. Add cutting oil by using oil gun during threading process.
6. When pipe is threaded in proper length, Switch the power off. Turn Carriage Hand Wheel to back Carriage away from Front Chuck, and disengage die head from pipe
7. Check if thread length is correct. Wash oil off the pipe.Wholesale Spare Parts
